APFIVE Polar Function Domain Restriction
The polar function $$r = 4\cos(2\theta)$$ represents a four-leaf rose. To graph only the right half of this rose (where $$x \geq 0$$), what domain restriction should be used?
A
0 ≤ θ ≤ π
B
0 ≤ θ ≤ π/2 and 3π/2 ≤ θ ≤ 2π
C
-π/4 ≤ θ ≤ π/4, π/2 ≤ θ ≤ 3π/4, and 5π/4 ≤ θ ≤ 3π/2
D
-π/2 ≤ θ ≤ π/2
